Take your time with the more difficult stretches. Just let your hands gradually build up to them. As with anything physical in nature, if you feel pain STOP. Give it at least a few minutes before continuing.
This kind of guitar study is gradual, so be sure to treat it that way.
I have included a TAB PDF download of the exercises, but make sure to watch the video to learn how to move the exercises up the fretboard. Pay close attention to the fret hand positioning, as that can make or break your ability to develop good legato technique.
Don't hurt yourself!! 😀
